Creating compute instances
|
||
|
|
--------------------------
|
||
|
|
|
||
|
|
First place your image into images pool path.
|
||
|
|
|
||
|
|
Create :file:`inatance.yaml` config file with following content. Replace `debian_12.qcow2` with your actual image filename.
|
||
|
|
|
||
|
|
.. code-block:: yaml
|
||
|
|

|
||
|
|
name: myinstance
|
||
|
|
memory: 2048
|
||
|
|
vcpus: 2
|
||
|
|
image: debian_12.qcow2
|
||
|
|
volumes:
|
||
|
|
- type: file
|
||
|
|
is_system: true
|
||
|
|
target: vda
|
||
|
|
capacity:
|
||
|
|
value: 10
|
||
|
|
unit: GiB
|
||
|
|
|
||
|
|
Check out what configuration will be applied when ``init``::
|
||
|
|
|
||
|
|
compute init -t
|
||
|
|
|
||
|
|
Initialise instance with command::
|
||
|
|
|
||
|
|
compute init
|
||
|
|
|
||
|
|
Also you can use following syntax::
|
||
|
|
|
||
|
|
compute init yourfile.yaml
|
||
|
|
|
||
|
|
Start instance::
|
||
|
|
|
||
|
|
compute start myinstance
|
||
|
|
|
||
|
|
Using ISO installation medium
|
||
|
|
`````````````````````````````
|
||
|
|
|
||
|
|
Download ISO image and set it as source for ``cdrom`` device.
|
||
|
|
|
||
|
|
Note that the ``image`` parameter is not used here.

|
|
::
|
||
|
|
|
||
|
|
compute init
|
||
|
|
|
||
|
|
Now edit instance XML configuration to add VNC-server listen address::
|
||
|
|
|
||
|
|
virsh edit myinstance
|
||
|
|
|
||
|
|
Add ``address`` attribute to start listen on all host network interfaces.
|
||
|
|
|
||
|
|
.. code-block:: xml
|
||
|
|

|
|
<graphics type='vnc' port='-1' autoport='yes' listen='0.0.0.0'>
|
||
|
|
<listen type='address' address='0.0.0.0'/>
|
||
|
|
</graphics>
|
||
|
|
|
||
|
|
Also you can specify VNC server port. This is **5900** by default.
|
||
|
|
|
||
|
|
Start instance and connect to VNC via any VNC client such as `Remmina <https://remmina.org/>`_ or something else.
|
||
|
|
|
||
|
|
::
|
||
|
|
|
||
|
|
compute start myinstance
|
||
|
|
|
||
|
|
Finish the OS installation over VNC and then do::
|
||
|
|
|
||
|
|
compute setcdrom myinstance /images/debian-12.2.0-amd64-netinst.iso --detach
|
||
|
|
compute powrst myinstance
|
||
|
|
|
||
|
|
CDROM will be detached. ``powrst`` command will perform instance shutdown and start. Instance will booted from `vda` disk.
